• Description:
  Sequential extraction was used in this U.S. Bureau of Mines study to determine the fractions of Cd, Pb, and Zn in abandoned Pb-Zn mill tailing amended with four types of organic residues, applied at three levels, with and without inorganic fertilizer. Trace element fractions selected for sequential chemical extraction were: (1) exchangeable, (2) dilute-acid extractable (bound to carbonates), (3) iron-manganese oxide bound, (4) organically bound, and (5) residual. Metal fractions in lead-zinc mill tailing change dependent upon organic residue type and rate of application. For all organic residue types, concentrations of Cd, Pb, and Zn in the Fe-Mn oxide and organically bound fractions increased as the rate of organic residue application increased, while concentrations of Cd, Pb, and Zn in the exchangeable and dilute-acid extractable fractions decreased as the rate of residue application increased. The results suggest that Cd, Pb, and Zn in abandoned Pb-Zn mill tailing will be prevalent in the weakly mobile, nonbioavailable forms as the rate of organic residue application is increased.
